Answer:
2/5 of a Mile
Step-by-step explanation:
Total mikes from school to Steven house = 3/5 of a Mile
If Steven walked 2/3 of the way there, the distance he walked =2/3×3/5 = 2/5
If he stopped the rest, then the distance he travelled before stopping is 2/5 of a Mile
Answer:
The mean of the sampling distribution is of 215 seconds and the standard deviation is 5.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
All songs
Mean 215 seconds, standard deviation 35 seconds
Sample

Mean 215, standard deviation 
The mean of the sampling distribution is of 215 seconds and the standard deviation is 5.
To find the new sides take the original sides and multiply it by the scale factor
12 * 1.5 = 18
10 * 1.5 = 15
14 * 1.5 = 21
So the new sides are 18, 15, 21. And they correspond to the 12, 10, and 14 respectively
Put the numbers in order.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 2: Find the median.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 3: Place parentheses around the numbers above and below the median.
Not necessary statistically, but it makes Q1 and Q3 easier to spot.
(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).
Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
(1, 2, 5, 6, 7), 9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.
Step 5: Subtract Q1 from Q3 to find the interquartile range.
18 – 5 = 13.
